Abstract

A light emission device and a display device using the light emission device as a light source are provided. The light emission device includes a vacuum vessel having first and second substrates (12, 14) and a sealing member (16), an electron emission unit (18) provided on an inner surface of the first substrate (12) and having driving electrodes (24, 26) and electron emission regions (28), a light emission unit (20) provided on an inner surface of the second substrate (14), a plurality of spacers (34) located between the first and second substrates (12, 14), and a resistive layer (36) formed on the first substrate (12) and coupled to at least one of the driving electrodes (24, 26). The resistive layer (36) surrounds a base of the spacer (34).
